Pluggable Brains - Huh?
by Edward Pollard 28 May '03

28 May '03

Well, I know they have a cool name. But thats about it. I have a problem that involves returning some data from a zCatalog, and some data from a Postgres database. Both items are treated as equivalent and should be displayed alphabetically side by side. I've got a marvelously kludgerific solution that involves copying the search results from the zCatalog into a list, which I can then insert my SQL based results in and sort as I see fit. I don't know if there is a better way, but I'd like to know more about Pluggable Brains so I can determine if there is. A search of Zope.org, and the list archives, comes up empty. Anyone with tips or resources? Edward

Storing published objects (?)
by Samir Mishra 28 May '03

28 May '03

Hello All, I'm not sure if the title accurately reflects what I want to do. I have a DTML method that uses a number of other objects and generates HTML code (the usual). What I'd like to do is assign/save the HTML code the method generates. I'd like to save the HTML as a BLOB in a database, and next time a user calls up a particular report, if the source data hasn't changed, publish the pre-rendered HTML. The underlying SQL queries are complex, the data doesn't change often, and I think this may be the best way to lighten the burden on the DB. Is this possible? If so, how would I go about accomplishing this? Perhaps there's a better way of accomplishing this? Thanks in advance. Regards, Samir

Pros and Cons of Different Hosting Solutions
by Rob Thorne 28 May '03

28 May '03

This is a topic that comes up every so often, but I'm curious to hear different people's experience. I'm starting to work with clients on Zope-based solutions, but don't yet have a good answer as to how best to host domains that use Zope. What are some of the pros and cons of these solutions that people on the list have found: * Custom Zope hosting (say, by exposing a part of the ZMI using a VirtualHostMonster) * Virtual Linux or BSD hosting where you install Zope yourself, probably with limited root access * Any other kind of arrangement folks are using that don't involve setting up your own ISP :-) What works well for folks, and what have people found to be best buy for themselves and for their clients? I've gone through the list of Zope Solution Providers, but this doesn't really tell me how to choose between them, or if I should be looking for something more general than any of them. Much thanks, Rob -- Rob Thorne Torenware Networks

uploading large files w/ LocalFS
by Mike Doanh Tran 27 May '03

27 May '03

Hi, I am trying to allow remote developers to upload large development tarballs onto our web server using LocalFS. The problem is when upload files are larger than 20MB the server times out. Does anyone have a better solution of allowing users to upload large files onto a Linux based webserver? Is https the right protocol for large file transfer? Any suggestions is greatly appreciated. Specs: Pent III 800 Mhz 128 MB Ram Zope using proxyPass through Apache Client's Browsers: Mozilla 1.1 & Konqueror 2.2.2 Thanks, Mike

Re: [Zope] Problem with cursor

That is the traceback we need. Unfortunately, I can't make much sense of it. Does 'my_query' work if it is called only once in that page? After a little bit of google searching, I've found two things: 1) http://mail.zope.org/pipermail/zope/2000-January/101259.html ZODBCDA has been doing this for a long time and no one has posted any (easily located) fixes. 2) http://www.zope.org/Products/DA/ZODBCDA ZODBCDA is free, but is old and hasn't been updated/bugfixed. It is a binary release, but is licensed ZPL - unusual. I wonder if the creator would release source for this... The other options I see would be to use freeTDS on a *nix system or purchase eGenix.com's mxODBC Zope DA.

dtml2python (sorry, forgot the subject)
by Dieter Fischer 27 May '03

27 May '03

Hello I didn't find the equivalent commands in python (script) for this two dmtl commands: <dtml-try> ... <dtml-except DatabaseError> <dtml-if "error_type == 'IntegrityError'"> ... </dtml-if> <dtml-else> ... </dtml-try> --- try: ... except DatabaseError: if error_type == 'IntegrityError': ... else: ... doesn't work. Have I to import something to access the variables, or what am I missing?

Acquisition and index_html in parent folder
by Oliver Keller 27 May '03

27 May '03

Hi, in the root folder i have an index_html that combines a "menu" file in the root folder and some files like "content" and "slogan" that can be found in subfolders. From a script called in "Somefolder" i tried a return statement like: return context.index_html So that the index_html (only beeing in the root folder) renders with "content" and "slogan" files found in "Somefolder". Unfortunately this return line gives me an NameError: "global name 'absolute_url' is not defined". I hope this can be fixed and i'm just missing something very obvious, oli -- "What're quantum mechanics?" "I don't know. People who repair quantums I suppose." --Terry Pratchett, "Eric"
